Kwaliteit en inspectie
Mar 21, 2018

Vier basiscategorieën van kwaliteitskosten worden hieronder beschreven:

1, Preventie ---- kosten gemaakt bij het plannen, implementeren en onderhouden van een kwaliteitssysteem dat de naleving van kwaliteitsvereisten op een economisch niveau garandeert. Een voorbeeld van preventiekosten is training in het gebruik van statistische procesbeheersing.

2, Beoordeling - gemaakte kosten bij het bepalen van de mate van conformiteit met kwaliteitsvereisten. Een voorbeeld van taxatiekosten is inspectie.

3, Interne fout --- kosten ontstaan wanneer producten, componenten en materialen niet voldoen aan kwaliteitseisen voorafgaand aan overdracht van eigendom aan de klant. Een voorbeeld van interne faalkosten is schroot.

4, Externe fout - kosten gemaakt wanneer producten niet voldoen aan kwaliteitseisen na overdracht van eigendom aan de klant. Een voorbeeld van externe faalkosten is garantieclaims.

Hoewel het niveau van kwaliteitscontrole grotendeels wordt bepaald door de waarschijnlijkheidstheorie en statistische berekeningen, is het erg belangrijk dat de gegevensverzamelingsprocessen waarop deze procedures zijn gebaseerd, passend en nauwkeurig zijn. De beste statistische procedure is waardeloos als er defecte gegevens worden ingevoerd, en net als bij machinale bewerkingsprocessen is het verzamelen van inspectiegegevens zelf een proces met praktische grenzen van nauwkeurigheid, precisie, resolutie en herhaalbaarheid.

Alle inspectie- en / of meetprocessen kunnen worden gedefinieerd in termen van nauwkeurigheid en herhaalbaarheid, net zoals een productieproces wordt geëvalueerd op nauwkeurigheid en herhaalbaarheid. Gecontroleerde experimenten kunnen worden uitgevoerd en statistische metingen van de resultaten kunnen worden uitgevoerd om de prestatie van een inspectiemethode ten opzichte van de te inspecteren onderdelen te bepalen. De geschiktheid van een of andere methode kan worden beoordeeld op basis van standaarddeviaties en betrouwbaarheidsniveaus die van toepassing zijn op elke benadering zoals gebruikt in een bepaalde inspectiesituatie.
